I own two sets of Brantly 248-404 main rotor blades with approximately 2,300 hours time remaining. Both have now been eddy current tested by Mark Bloodgood (mark@talontestlab.com), Talon Test Laboratories, Inc., Phoenix, Arizona, in accordance with FAA AD 2014-20-16 and Authorized Release Certificates, (FAA Form 8130-3s), have been issued for both sets. Each set cost $202.50, the company was nice to work with, and I left my calibration standard with them so if other Brantly owners need testing they can use my standard for an extra charge of $50, which is far less than it costs to make one. In addition, Talon has other locations in the U.S., so you are welcome to coordinate things with someplace closer and I will tell Mark to loan my calibration standard to his associated labs. All my handwringing over this AD was a big waste of time.
